BACKGROUND Field

The example embodiments in general are directed to a material covering for a kettlebell weight, namely a weighted vest, sleeve or wrap attachable around a fixed or adjustable weight kettlebell to change its existing weight.

Related Art

A kettlebell is a type of dumbbell or free weight that is round with a flat base and an arced handle. It looks like a cannonball with a handle, or a teapot without the spout, hence the name “kettlebell” in English. In Russia (where it originates) the Russian kettlebell is called a “girya”. Authentic kettlebells are made of either cast iron or steel. FIG. 1 shows an example of a range of conventional kettlebells from about 15 to 50 pounds.

The Russian kettlebell as known today originated approximately 350 years ago, and was originally used as handled counterweights to weigh out dry goods on market scales. Over the following three centuries, kettlebells began to be used for exercise, entertainment and lifting competitions. Shortly after the end of World War II, modern kettlebell lifting became the Soviet Union's national sport. Today, Russian Military requires its recruits to train with kettlebells. The United States Secret Service & the FBI Counter Assault Team also require their operators to train with high repetition, ballistic kettlebell moves.

Unlike a dumbbell, a kettlebell's center of mass extends beyond the hand. Kettlebells can be swung, thrown, juggled, pressed, held, moved and manipulated in hundreds of ways. They are small and portable and are now being incorporated into all aspects of athletic and fitness training. Kettlebells are a highly efficient way to lose weight, tone the body, increase cardio-vascular fitness and strength and maintain joint health, mobility and flexibility.

Kettlebells can be configured as a fixed weight or and be adapted to have weight added or removed therefrom, hence adjustability. In one example, weighted add-ons (typically cylindrically-shaped) can be attached to the bottom of a kettlebell to change its total weight, in an effort to avoid having to purchase higher-weighted individual kettlebells. In another example, adjustable Russian kettlebells are even more economical. This type of kettlebell typically ranges from 10 to 40 pounds, due to its 10-pound handle and base, and includes six 5-pound plates so a user may progress at a natural and gradual pace. The adjustable kettlebell also has is a locking device to add and remove weights allowing the user to quickly change weight between workout sets.

However, the adjustable kettlebells can be expensive, and since kettlebells come in a variety of weights, as shown in FIG. 1, the cost of maintaining a suite of differently weighted kettlebells could be prohibitive. What is needed is a kind of weighted covering, wrap, sleeve, or vest type article configured to be attachable around a kettlebell.

SUMMARY

An example embodiment of the present invention is directed to a covering for a kettlebell weight having a weighted body and attached handle. The covering includes a generally elongated fabric wrap adapted to be oriented around an outer circumference of the weighted body so as to envelop the kettlebell therein. The fabric wrap is weighted so as to change the overall weight of the kettlebell once secured thereto. A securing mechanism is attached to the fabric wrap to secure the fabric wrap in close contact around the weighted body.

Another example embodiment is directed to a kettlebell vest for attachment to a kettlebell weight. The kettlebell vest includes a generally elongated fabric wrap adapted to be oriented around an outer circumference of the kettlebell weight. The fabric wrap is embodied as a multi-layered construction of fabric layers. At least one layer of the fabric wrap provides added weight within the interior of the kettlebell vest.

Another example embodiment is directed to a kettlebell vest for attachment to a kettlebell weight. The kettlebell vest includes a weighted multi-layer fabric wrap adapted to be oriented around an outer circumference of the kettlebell weight. The kettlebell vest includes one or more elastic straps attached to multi-layer fabric wrap so the kettlebell vest is configured to accommodate differently sized kettlebell weights.

DETAILED DESCRIPTION

The example embodiments hereafter describe in general a material covering for a kettlebell weight, synonymous with or otherwise known as any of a weighted vest, sleeve, or wrap attachable around a fixed or adjustable weight kettlebell to change its existing weight. The kettlebell vest includes an inter weighted fabric layer 103 that is composed of a plurality of sections or individual pockets (hereafter “cells 103 a”), each cell 103 a containing a pouch filled with a loose material having weight.

FIGS. 2-13 are provided to show unique features, constituent components, and example materials for the material covering for kettlebells (“kettlebell vest 100”). These figures describe only an exemplary kettlebell vest construction; numerous other constructions are foreseen in accordance with the example embodiments.

As previously described, kettlebells are available in adjustable weights and in fixed weights, thus the ability for adding additional weight to a fixed weight (or even adjustable weight) kettlebell is anticipated by the example embodiments. The ability to add weight in increments helps kettlebell users reduce the number of kettlebells they require. For example, rather than owning a 201 b, 251 b and 301 b kettlebells, a user of the kettlebell vest 100 may simply utilize a 51 b vest (or also a 101 b vest, as the 51 b and 101 b versions are likely most commercially feasible) and own 201 b and 301 b kettle bells only, however they will have the ability to use kettlebells at 20, 25, 30 and 351 b weights.

Kettlebell vest 100 includes a securing mechanism attached to the fabric wrap 101 to secure the fabric wrap 101 in close contact around the weighted body 205 of kettlebell 200. As shown, the kettlebell vest 100 is configured so as to be attached directly to the kettlebell 200, with any number of securing mechanisms to secure it thereto, only one of which is shown (a quick lock assembly). This quick lock assembly may be composed of a cord 130, which is threaded through a plurality of facing eyelets 120, the eyelets arranged as vertical columns at the edges or mating ends 108 a, 108 b of the kettlebell vest 100. A button toggle cord lock 135 may be used to secure cord 130 in tight locked fashion once the excess cord is pulled tight, as is known. A woven pocket 118 on outermost layer 102A adjacent eyelets 120 is provided to insert any extraneous cord 130 below the button toggle cord lock 13.5 Of course, one or more of more clasps, fasteners, straps, magnetic devices, Velcro, clips or other such items may be used in lieu of or in conjunction with the quick lock assembly described in the figures.

As shown, the kettlebell vest 100 is adapted to be arranged around and cover the kettlebell 200, which has a weighted body 205 and attached handle 210. Vest 100 includes a generally elongated fabric wrap (element 101) that is adapted embodied as a multi-layered construction of fabric layers with foam portions therein, see for example the outermost layer, a waterproof nylon layer 102A in several of the figures. The multi-layered fabric wrap 101 is to be oriented around an outer circumference of the weighted body 205 so as to envelop the kettlebell 200 therein. In this example, the fabric wrap 101 is weighted so as to change the overall weight of the kettlebell 200, once the kettlebell vest 100 is secured thereto.

The kettlebell vest 101 includes one or more elastic straps attached to the multi-layer fabric wrap 101 so that the kettlebell vest 100 is configured to accommodate differently sized kettlebell 200 weights. Namely, and referring to FIGS. 5 through 9, the kettlebell vest 100 includes a pair of elastic binding members 107 and 109 arranged along each upper and lower longitudinal edge of the fabric wrap 101. A pair of webbing straps 110 with clasps 112 are attached to the upper elastic binder member 107 by double stitching 119. At least one or more (two shown in crossed relation) elastic straps 125 are attached on the underside to the edge of the lower elastic binding member 109 by the aforementioned double stitching 119. Accordingly, these straps 110 and 125 enable the kettlebell vest 100 to accommodate differently sized (diameter) kettlebells 200.

The fabric wrap 101 may be embodied as a multi-layered construction of fabric layers 102A, 102B, 103, with foam portions 104 therein. The multi-layered construction of fabric layers that make up fabric wrap 101 (waterproof or water-resistant layers 102A (outermost) and 102B (innermost), a weighted interior layer 103, and one or more foam portions 104) is bound together at layer edges thereof by the aforementioned elastic binding members 107 and 109 along the upper and lower longitudinal edges of the fabric wrap 101. It is desirable that double-stitching 119 forming a seam (such as French seams) secure the multi-layered construction of fabric layers that make up fabric wrap 101 to the elastic binding members 107 and 109, so that no double-stitched seams burst during the used lifetime of the kettlebell vest 100.

In one example, the waterproof or water-resistant outermost and innermost layers 102A and 102B may be made of nylon. Nylon and polyester are water resistant because of their tight weave. But with a special coating, these fabrics are made waterproof. A layer of polyurethane is used to cover the interior of the fabric. More specifically, in an example, the outermost layer 102A (and innermost layer 102B) may be made of a ripstop nylon fabric. Ripstop nylon, which was used originally in WWII to make parachutes, is a sturdy lightweight wind-resistant fabric made of nylon fibers. After it is given a waterproof coating, it is unstoppable as a rough and tough fabric. The fabric has a grid design in its weave.

An alternative material for layers 102A and 102B may be a PVC coated polyester fabric. PVC-coated polyester is a waterproof, 100% polyester fabric with poly- vinyl chloride coating on the elements-facing surface. It is slightly stiff but has a smooth finish on the inside. A further nylon-type material usable for layers 102A and 102B is terylene. Terylene is a densely woven polyester fabric, typically used to make sails, sunshades, canopies, awnings, etc. because of its water proof quality.

Of course, nylon and polyester based materials are only exemplary; the example embodiments are not so limited. Waterproof or water-resistant layers 102A and 102B may be constructed of materials including but not limited to polyester or cotton polyurethane laminate (PUL), thermoplastic polyurethane (TPU), waxed canvas, laminated poplin/cotton, oilcloth, microfiber, wool, vinyl, pleather (Naugahyde), plastic, and densely woven branded fabrics, or combinations thereof.

Fabric wrap 101 may include one or more fabric panels 117 having non-slip properties. Examples of materials for panels 117 include those made out of 100% expanded PVC to provide a non-skid, slip resistant fabric. Alternative non-slip materials for panels 117 may include but are not limited to any of thermoplastic polyolefin (TPO) laminated with polyester/nylon, non-slip treated rubber, non-slip-treated vinyl, and the like.

The weighted interior layer 103 is the layer that adds weight to the kettlebell vest 100. Namely, and referring to FIGS. 5, 6 and 11, the weighted interior layer 103 may be made of a fabric having a plurality of individual stitched cells 103 a (also called “pockets”), each cell 103 a filled with at least one sealed plastic packet 123 of a loose material having weight, as best shown in FIG. 12. The individual cells 103 a are arranged in one example, in different sizes so as to accommodate differently sized sealed packets 123. The sealed plastic packets 123 are robust as they are sealed via a thermoweld. This prevents any of the loose, weighted material (shown in FIG. 12 as a sand 124 such as chromite sand) from leaking out or even moving around within weighted interior layer 103.

In an example, the weighted interior layer is 103 composed of a non-woven composite fiber material, that, with the plurality of individual cells 103 a formed therein and filled with a loose material such as sand, renders the total weight of the kettlebell vest 100 to be at least 51 b and in an example within a range of between five and ten pounds. Namely, the weighted interior layer 103 may be composed of a rip stop nylon. One example of such a material is a DYNEEMA® composite fabric, originally known as Cuben fiber (hereafter “composite fiber material”). DYNEEMA is a high-performance non-woven composite fiber material used in high-strength, low-weight applications. The composite fiber material is constructed from a thin sheet of ultra-high-molecular-weight polyethylene laminated between two sheets of polyester.

More specifically, the material is a laminated fabric constructed from ultra-high molecular weight polyethylene (UHMWPE) fiber monofilaments and polyester, polyvinyl fluoride, etc. films. The fiber is up to 15 times stronger than steel on a weight for weight basis. DYNEEMA floats on water and is extremely durable and resistant to moisture, UV light and chemicals.

Referring to FIGS. 7 and 8, the dotted-line area 113 a represents a reinforced eyelet panel 114, and the dotted-line area 113 b denotes another area, that, like area 113 a around the eyelet panel 114, is free from any of the sand packet 123-filled cells 103 a of the weighted interior layer 103. This enables the eyelet panel 114 to provide a strength that prevents the facing columns of eyelets to pull away from each other. On the opposite right side, a central seam 115 of double stitching 119 (with no packets 123 present in area 113 b), permits the kettlebell vest 101 to fold in half for storage.

As shown in FIG. 10, fabric wrap 101 includes form portions 104. In an example, these foam portions 104 may be embodied as one or more internal open-cell foam wedges 104. These wedges 104 are inserted around the weighted interior layer 103 on one or both sides thereof to improve appearance, namely so as to fill gaps within the interior between layer 103 and bounding outer and innermost layers 102A and 102B. These gaps are created when the kettlebell vest 101 (without foam portions 104) is wrapped around the kettlebell 200. Insertion of various foam wedges 104 present a smooth interior and exterior appearance inside of the outermost and innermost layers 102A respectively.

The example embodiments having been described; it is apparent that such have many varied applications. For example, although kettlebell vest 100 has been described in terms of having the weighted fabric layer 103 of stitched individual cells 103 a, the exterior nylon layer 102A could be configured with multiple pockets or sleeved sections thereon to hold one or more additional exercise weights therein.
